To determine the relationship between dentin hypprsensitivity and gingival recession, 70 subjects (358 teeth) were examined in Tokushima University Hospital and Fukumoto Dental Clinic. The result showed that cold stimulus index per subject (y) was positively con-elated with the mean levels of gingival recession (x), indicating y=0.188x+0.194. When the teeth were individually analysed, the teeth with gingival recession showed a higher response against cold stimulation compared with those without gingival recession. In addition, the greater level of gingival recession, the higher response was observed. These findings suggest that onset and intensity of dentin hypersensitivity may be associated with the levels of gingival recession.

为探讨牙本质过敏症与牙龈退缩的关系，对德岛大学附属医院和福本牙科门诊的70名受试者（358颗牙）进行了检查。结果表明，冷刺激指数（y）与牙龈退缩程度（x）呈正相关，y=0.188x+0.194。当牙齿单独分析时，牙龈退缩的牙齿对冷刺激的反应比没有牙龈退缩的牙齿高。此外，牙龈退缩程度越大，观察到的反应越高。这些结果表明，牙本质过敏症的发病和强度可能与牙龈退缩的水平。
